138 +* Mean level threshold – TM level, A (if module of instantaneous current (I,,I,,) which is received from shunt sensor is between T,,M,, and T,,0,,, BMS will use mean value of current I,,M,,; if I,,I,, is greater than T,,M,,, BMS will use instantaneous value of current I,,I,,);

140 +* Sensor state:
141 +** Online – a flag showing that the communication with the BMS Current Sensor is established;

143 +** Current – an instantaneous value of current measured by the BMS Current Sensor, A (measuring frequency is 50 Hz);
